The equation v(x)=32500(0.92)^x how much more is the truck worth after two years than after three years
Lyrx [107]

Answer:

the difference:  $2,192.64

Step-by-step explanation:

After 1 year, the truck has lost 8% of its value:  v(x) = $32,500(0.92)^1, or

$29,900.

After 2 years, v(x) = $32,500(0.92)^2, or $27,500.  Finally, after 3 years,

v(x) = $32,500(0.92)^3 = $25,307.36.

Subtracting $25,307.36 (the value after 3 years) from $27,500 (the value after 2 years) yields the difference:  $2,192.64

Which item is more economical?
iVinArrow [24]
The correct answer is: <span>a $100,000 life insurance policy at $0.55 per $1000 per month (more economical)

</span>
Explanation:

(1)<span>a $100,000 life insurance policy at $0.55 per $1000 per month

It means:
$0.55*100*12  = $660 [There are 100 thousands in $100000 and there are 12 months in the year]

(2)</span><span>a $100,000 life insurance policy at $170 per quarter.

It means:
$170*4 = $680 [There are 4 quarters in a year]

As $680 > $660 therefore Option (A) is the economical option.</span>

PLEASE HELP! 20 points!
andreyandreev [35.5K]

Answer:

Step-by-step explanation:

The marks on both sides of the triangle shows that the sides are equal. This means that the triangle is an isosceles triangle.

This means that

x = 4

Also, in an isosceles triangle, the base angles are equal. Therefore, the sum of the base angles would be 2y.

The sum of angles in a triangle is 180 degrees. Therefore,

2y + 50 = 180

Subtracting 50 from both sides of the equation, it becomes

2y + 50 - 50 = 180 - 50 = 130

2y = 130

y = 130/2 = 65 degrees.
